Sherdog: Alistair Overeem.
Shamrock: A killer. Has the potential to be a superstar, but Iím not sure heíll do it. If his focus is purely on fighting, he could. But I donít think he sees whatís going on in the U.S., the huge growth of the sport. I hope he does. Heís got great technique, heís massive and people love him. He looks the part and can fight. Most big guys canít fight. They look like they can fight, but they canít move. Heís a rare breed. Most big guys donít have to fight people, so they donít have the same urgency to train hard. Iíll fight a big guy any day over a medium-sized dude who has to scrap. We Americans, we love the big guy. He could be a huge hit here.
